NEET 2022 Botany Alternation of Generations Match the Following Question
Match the plant with the kind of life cycle it exhibits:
| List-I | List-II |
|---|---|
| (A) Spirogyra | (I) Dominant diploid sporophyte vascular plant, with highly reduced male or female gametophyte |
| (B) Fern | (II) Dominant haploid free-living gametophyte |
| (C) Funaria | (III) Dominant diploid sporophyte alternating with reduced gametophyte called prothallus |
| (D) Cycas | (IV) Dominant haploid leafy gametophyte alternating with partially dependent multicellular sporophyte |

Correct Answer
Detailed Explanation
Chapter: Plant Kingdom
Class: 11 | Topic: Life Cycles | Difficulty: 🟡 Medium
✅ Ans: D — (A)–II, (B)–III, (C)–IV, (D)–I
- Spirogyra → II: Dominant haploid free-living phase.
- Fern → III: Dominant diploid sporophyte; gametophyte is prothallus.
- Funaria → IV: Dominant haploid leafy gametophyte; sporophyte is partially dependent.
- Cycas → I: Dominant diploid sporophyte with highly reduced gametophytes.
📌 NCERT: Plant life cycles show alternation between haploid gametophyte and diploid sporophyte phases.
🧠Quick Revision: Spirogyra → Haploid dominant Funaria → Gametophyte dominant Fern → Sporophyte + prothallus Cycas → Sporophyte dominant
Correct: D.
